Check Digit Verification of cas no

The CAS Registry Mumber 74189-77-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,8 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74189-77:
(7*7)+(6*4)+(5*1)+(4*8)+(3*9)+(2*7)+(1*7)=158
158 % 10 = 8
So 74189-77-8 is a valid CAS Registry Number.

Carbocyclic phenylaminephosphonate stereochemistry as probed via 13C nmr chemical shifts and nuclear spin couplings from 13C to 31P and 15N

Buchanan, Gerald W.,Morin, Frederick G.

, p. 530 - 536 (2007/10/02)

13C nmr chemical shifts and 13C-31P couplings through one, two, and three bonds are reported for eleven carbocyclic phenylaminephosphonates with ring sizes from four to seven.On the basis of these data, inferences regarding preferred conformations are drawn.Low temperature spectra of the 4-methylcyclohexyl derivative show the existence of two conformers, populated in the ratio of approximately 2:1 at 183 K.
